Means non OPENING TIN cans.

Specification of Letters Fatent. Patented Get. 17, l lln 2 Applicationfiled March 16, 1916. Serial No. 84,505.

To all whom it may concern Be it known that I, Tndgms Orrnsian, a

subject of HisMajesty the I ing of Norway,

residing at Lervigsveien l1, Stavanger, Norway, a manufacturer, haveinvented a certain Improved Means for Opening Tin Cans; and I do herebydeclare the following to be a full, clear, and exact description of thein: vention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to means for opening tin cans, of the kindwherein an opening tongue is provided by weakening lines in the lidinclosing a tongue shaped area, which tongue after being partiallybroken away from the lid is adapted to be engaged by a key for thecompletion of the opening oper-- ation.

The invention difl'ersafrom arrangements known before, in that a secondweakening line, extending at right angles tothe longitudinal center lineof the tongue shaped area, has its ends turned laterally away from thetongue and extended to the seamed edge of the lid. A smaller area isthus inclosed, which ugien pressed downwardly by the opening ey is tornaway along the said second weakening line and bent inwardly into thecan,thereby providing an aperture into which the opening key may be insertedso as to lever up, the end of the tongue sh, ped area ivnichtmayafterward be torn away in the usual manner by engaging said tongue endwith a slot formed in the key stem and rotating the latter about itsaxis.-

In the annexed drawings which-show a tin can in accordance with thisinvention ze- Figure l is a plan view of the can, Fig. 2 is alongitudinal tection thereof before opening, Fig. 3 shows a similarsection after the opening has been commenced, and Fig. 4

shows a convenient construction of opening key.

The ends of'the weakening line 1 are arranged in the lid as usual, andinclose a tongue shaped area, and terminate at a second weakening line 2extending transversely of the longitudinal center .lineof the tongue.

The ends of this transverse weakening, line are turned laterally awayfrom the tongue and extended to the seamededge 8 of'the lid, therebyinclosinga smaller area 3. When pressed downwardly by the opening key 4(Fig. 2) this smaller area 3 will be torn away from the lid along theweakening line 2 and bent inwardly into the can. The end of the openingkey' is then inserted through the aperture thus formed, and the end 5 ofthe tongue shaped part of the lid is levered up by the key, as shown inFig. 3, into position for engagement by the slot in the key stem, whenthe openingfoperation is completed the usual way by rotating the keystem about its axis. The tongue shaped part is advaii- 65.

tageously provided with a depression 6 which affords a good hold for thekey during the completion of the opening operation.

Vvhile the weakening lines 1 in the lid are usually pressed intothe'under face of the lid,

"the weakening line 2 is, as shown, pressed. into the upper face. Thearea 3 is, therefore,

when pressed downwardly,'more easily torn loose along the-weakening line2 than. were the latter pressed. into the under. face of the lid. i I uU An ordinary opening key maybe used; it"

will, however, be preferable to use a key," as'" v 1.
